AUGUST H. DAHL AND ARTHUR E. WHITELY, OF NEW YORK, N. Y.,

ASSIGNORS OF ON E-TENTH TO CHARLES 0. DAIIL, OF NEW YORK,

CONVEYER.

Patented June 11, 1907.

Application filed May 2,1906. Serial No. 314,877.

To all whom it may concern:

Be it known that we, AUeUsr H. DAHL and ARTHUR E. WHITELY, citizens ofthe United States, residing at New York, in the county of New York andState of New York, have invented certain new and useful Improvements inConveyers; and we do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to conveyers, and

hasfor an object to provide a conveyer adapted for use in connectionwith building and structural operations and for hoisting and conveyingbuilding and structural material to and about a building in course ofconstruction.

A further object of the invention is to provide a conveyer of the classdescribed embodying a track arranged to embrace and encircle thebuilding under construction and a carriage arranged to move about saidtrack and about said building and embodying a derrick carried upon saidcarriage.

A furtherobject of the invention is to provide a carriage for operationupon a track of the class described, provided with a derrickmast erectedthereupon, and means for retating the derrick upon'its mast or the mastupon the carriage, and with means for moving the said derrick about thetrack, and for operating the derrick portion of the carriage.

A further object of the invention is to provide a track arranged insections for interchangeable connection to permit of expansion andcontraction of the track for use on buildings of different sizes andprovided with means for supporting said track at the necessary heightrelative to said building.

With this and other objects in view, the invention comprises certainnovel, constructions combinations and arrangements, as will behereinafter fully described and claimed.

In the drawings: Figure 1 is a view of the improved conveyer in sideelevation. Fig.2 is a top plan view of the improved conveyer.

. Fig. 3 is a vertical, sectional view of the improved conveyer, takenon the line 3-3 of Fig. 2. Fig. 4 is a perspective view of the carriageand derrick associated therewith. Fig. 5 is a detail view of the trackconstruction.

Like characters of reference designate corresponding parts throughoutthe several views.

In its preferred construction, the device forming the subject matter ofthis application comprises a track designated as a whole at andcomprising an I-beam 11 having an upper double flange 12 and lowerflange l3, wider than the upper flange. The track 10 is composed ofsections interchangeable and adjustable with joints as shown at 14, thesaid sections being held in operative relation by means of plates, as15, bolted to the inside of the lower flange 13, as by the bolts 16. Thesections'are provided with overlapping tongues 17 formed in the web ofthe I-beam and with the flange sections overlapping as at 18 to permitof their being engaged by the bolts 16. The track is supported in anysuitable manner, as by being rigidly attached to the structural frame ofthe building upon which it is being used, or is provided withindependent means of support, as the struts 19, preferably formed ofsheet metal curved lon itudinally, as shown particularly in Fig. 2, i orthe purpose of rendering the said struts the more rigid. The struts arebraced in any suitable manner against lateral displacement, as by thebraces 20, and the track is supported thereupon in any approved manner,as by forming slots 21 in the curved face of said struts and providingthe track portion with brackets 22 positioned to embrace the said strutson opposite sides and connected by means of the bolt or pin 23,proportioned for engagement within the slots 21.

Upon the track formed of the I-beams 11 is mounted a carriage shown as awhole at 24, and comprising a body portion provided at opposite endswith cross-heads 25 curved downwardly, affording at their opposite endsears 26, to which are journaled rollers 27 positioned to bear andoperate upon the lower flange 13 of the Lbeams. Within the downwardlycurved portion of the cross heads 25 are formed bearing members 28 towhich are journaled vertical rolls 29 positioned to bear against the webof the I-beam 11 and prevent lateral displacement of the carriage.

Upon the carriage 24 is mounted a tubular upright 30 within which isrotatably mounted a mast 31 having at its lower end a ratchet wheel 31engaged by a pawl 32 pivotally mounted upon a carriage 24 and by whichthe mast 31 is held against rotary displacement.

The mast 31 is provided at its upper end with a boom 33 with itsopposite ends extending upon opposite sides of the mast andprovided withpulleys 34 and 35 and with cable guides 36 and 37. Upon the upright 30is provided an arm 38 rigidly extending therefrom and having a pulley 39rotatably mounted in its bifurcated extremity.

Extending about and above track 10 is a sprocket chain 40 carried ateach corner of t e said track by idlers 41 and operated by means of asprocket 42 preferably mounted at one corner of the track and rotated bymeans of a shaft 43 extending downwardly through the said track andprovided at'its lower end with a gear 44 engaging a similar gear 45 uponthe shaft 46 which is operated by a sprocket 47 over which is passed asprocket chain 48 engaging at its opposite end a sprocket 49 rotatedfrom any convenient source of power, as the conventional engine 50.Extending about and above the track is also a cable 51 carried at thecorners upon idlers 52 and having one of its ends extending through thepulley 39, then upwardly over the pulley 35 and downwardly over theulley 34 and engaging any load, as a buc ret 53. After passing about thetrack structure over the idlers 52 as noted,

the opposite end of the cable passes over a pulley 54 journaled upon abracket 55 rigidly carried by the track 10. The cable 51 passes downwardas at 56 and about a drum 57 which is mounted upon the shaft 58 by meansof any improved clutch mechanism.

Upon the mast 31 is mounted a slidable plate 59 provided With a slot 60engaged upon a pin 61 held normally at the upward extremity of itsmovement by means of a spring 62. The upper end of the plate 59 ispivotally secured to a lever 63 which is pivoted at its opposite end, asto pin 64, and provided with a curved finger 65 ositioned to engage theupper surface 0 the boom 33 when the plate 59 is drawn down- I wardlyagainst the tension of the s ring 62.

In its operation, the carriage is he din any approved operative positionby means of the sprocket chain 40, and the bucket or other load, asshown at 53, raised or lowered as may be required. When the load hasbeen raised to operat ve position the carriage 24 and its associatedmast and load are moved about the track in the direction of the arrow,the said load being held at the required height by reason of the drum 57being of the same diameter as the sprocket 49 and the intermediategearing being so proportioned that the cable 51 moves at the same rateas the sprocket chain 40. When the load 53 has reached its desiredposition, the boom 33 may be rotated as required by disengaging the pawl32 and thereby releasing the ratchet 31. When the load has been releasedfrom the cable 51 the said carriage is returned by a reverse movement ofthe drum and sprocket and another load raised and moved in like manner.
